Just need some information here. Basically I’m running 2x 18 player servers on the dedi which is an AMD Athlon 64 Processor 3400+ with a gig of ram.

The server isn't lagging i.e. the CPU usage of 10/18 players is around 10 % and the other server say 6/18 players is 3% CPU.

People complain of lag like 300 pings but the server box isn't lagging itself. I've had an idea of putting it on a higher CPU priority. The high pings only last for a few seconds but the overall ping is quite high.

I've read your other post. I am still not sure about your network. You say its on a fibre optic cable, but I am still not sure whether you are renting this server from somewhere, or whether its in your house on your home DSL line. If its on your home DSL line, then you will definitely get high pings if you have more than half a dozen or so players. If you are renting a server from somewhere, ask them what your upstream speed is.

[Edit]With the spec of your machine, you might be able to get away with a tick rate of 100.

I have server racks in redbus so im fairly certain i know what type of bandwidth your host has ... and its damn good bandwidth leading me to believe there is a problem directly with the upstream port speed you have been allocated. i.e it isnt enough. If you signed a contract whereby you have a 1 or 2mb port it will begin to lag when more players join.

Ask your host your upload speed and ask if you are on 'infinity' bandwidth ... are you on a 195.62.10.* ip address? just so i know

I'm preety sure that's not it since one of the boxes I'm talking about is on dedicated 100mbit and the other one is an ISP box with like a 100mbit link to a terrabyte backbone or something. Nothing else lags on the box - its just this damm source server :|
